JavaScript Date setUTCSeconds()方法

下面是一个例子 日期设置秒() 方法

null
  • 例子:

    javascript

    <script>
    // Here a date has been assigned according to
    // universal time while creating Date object
    var dateobj =
    new Date( 'October 13, 1996 05:35:32 GMT-3:00' );
    // New second of 52 is being set in above Date
    // Object with the help of setUTCSeconds() method
    dateobj.setUTCSeconds(52);
    // New second from above Date Object is
    // being extracted using getUTCSeconds()
    var B = dateobj.getUTCSeconds();
    // Printing new Second
    document.write(B);
    </script>

    
    

  • 输出:
    52

这个 日期setUTCSeconds() 方法用于根据通用时间将秒设置为日期对象,该对象是使用date()构造函数创建的。

语法:

DateObj.setUTCSeconds(seconds_Value);

参数: 该方法接受一个参数,如上所述,如下所述:

  • 秒值: 此参数保存第二个值,我们希望在使用date()构造函数创建的日期中设置该值。

返回值: 它返回由setUTCSeconds()方法设置的新的即更新秒数。

注: 这个 DateObj 是使用Date()构造函数创建的有效日期对象,我们希望在其中设置第二个。秒的值从0到59。

以上方法的更多代码如下:

项目1: 如果在Date()构造函数中,我们在创建Date对象时没有给出任何秒,那么setUTCSeconds()方法将能够根据创建的Date对象中的通用时间设置新秒作为其参数。

javascript

<script>
// Here second has not been assigned according to
// universal time while creating Date object
var dateobj = new Date( 'October 13, 1996 GMT-3:00' );
// New second of 51 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(51);
// New second from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Printing new Second
document.write(B);
</script>


输出:

51

项目2: 如果Date()构造函数中没有给出任何参数,那么setUTCSeconds()方法将能够设置秒,但月份、年份、日期等仍然是当前的。 这里42是新的第二个,3是当前月份,即4月,1是当前日期,2018年是世界时的当前年份。

javascript

<script>
// Here nothing has been assigned
// while creating Date object
var dateobj = new Date();
// New second of 42 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(42);
// Seconds from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Month from above Date Object is
// being extracted using getUTCMonth()
var C = dateobj.getUTCMonth();
// Date from above Date Object is
// being extracted using getUTCDate()
var D = dateobj.getUTCDate();
// Year from above Date Object is
// being extracted using getUTCFullYear()
var E = dateobj.getUTCFullYear();
// Printing new seconds
document.write(B + "<br />" );
// Printing current month
document.write(C + "<br />" );
// Printing current date
document.write(D + "<br />" );
// Printing current year
document.write(E);
</script>


输出:

42
3
1
2018

方案3: 如果second 66的值作为setSeconds()方法的参数给出,它会将6设置为second,因为第二个范围是0到59,因此 66-60=6 ,这里减去60,因为0到59是60。

javascript

<script>
// Here date has been assigned according to
// universal time while creating Date object
var dateobj =
new Date( 'October 13, 1996 05:35:32 GMT-3:00' );
// New second of 66 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(66);
// Seconds from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Minute from above Date Object is
// being extracted using getUTCMinutes()
var C = dateobj.getUTCMinutes();
// Printing new seconds
document.write(B + "<br>" );
// Printing minutes
document.write(C);
</script>


输出:

6
36
